# Run A Bash Script From A Node Script
|
|
|
|
A node script in `package.json` can reference and run any command or executable
|
|
script available on our system. This is why we're able to have node scripts
|
|
that do things like run a linter or start a web server.
|
|
|
|
We can take this a step further by defining our own scripts to enhance our
|
|
development and CI environments.
|
|
|
|
For instance, let's say we have the following bash script (`check-stripe`) in
|
|
our project's `scripts` directory for checking that we are connected to the
|
|
right Stripe account.
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
|
|
# Expected stripe display name
|
|
EXPECTED_STRING="My Online Product"
|
|
|
|
# Currently connected stripe display name
|
|
COMMAND_OUTPUT=$(
|
|
stripe config --list | grep '^display_name' | awk -F'=' '{print $2}' | xargs
|
|
)
|
|
|
|
# Compare the expected string with the command output
|
|
if [ "$EXPECTED_STRING" = "$COMMAND_OUTPUT" ]; then
|
|
exit 0
|
|
else
|
|
echo "Mismatched Stripe accounts, expected $EXPECTED_STRING, got $COMMAND_OUTPUT."
|
|
exit 1
|
|
fi
|
|
```
|
|
|
|
This script exits with either a successful (`0`) or failed (`1`) status. We can
|
|
use this in our node script to guard another command from getting run.
|
|
|
|
```json
|
|
{
|
|
"scripts": {
|
|
"dev:stripe": "./scripts/check-stripe && stripe listen ..."
|
|
}
|
|
}
|
|
```
